Sen. Dianne Feinstein, D-California, is set to introduce her bill to reinstate a federal assault weapons ban on Thursday.

Feinstein announced her plans to introduce the ban after December’s mass shooting in Newtown, Conn. President Barack Obama has also called for a ban on weapons that resemble military firearms.

The bill will call for the prohibition of 120 specific weapons, magazines that can carry more than 10 cartridges and firearms that can accept a detachable magazine in addition to at least one other military-style feature. Feinstein’s office has also revealed that while the bill would not mandate the confiscation of pre-ban weapons, it would require registration of any grandfathered weapons.
